Rather than a Benny B. at the Central Bank and a Timmy G. at the Treasury, perhaps some old-school and real thinking men are needed at the printing presses (or in those days, printing mills):

John Locke — philosopher and secretary to the Chancellor of the Exchequer (Lord Ashley), secretary/commissioner of the Board of Trade, adviser to the Great Recoinage of 1696;Issac Newton — mathematician and Master/Warden of the Royal Mint, who enforced the Great Recoinage of 1696.
